Apart from charging top dollar for a domain I had to have, I experienced none of the problems others have. The sale went through quickly without a hitch and I subsequently transferred the domain to another registrar within days.
I see no problem with this site for children other than it's not one in which they would be interested.
However, reading the other comments here, if true, you may need to exercise extreme caution when dealing with them.
Absolute scam. These guys are fully engaged in the cybersquatting game! BEWARE they are complete scammers. Do not buy any domains from at any cost. There are lots of complaints against the site owners for fraudulent activity. Every customer is complaining about their non-existent customer service.
